In this "Dark Knight"-themed episode, Lindsay and Stephen tackle auto innovations of all varieties. These include GM's plans to build a windshield that can enhance a driver's vision; a new movie about one man's battle with the auto industry over his invention of the intermittent windshield wiper; Audi's smart traffic light system; and the future prospects of a plug-in hybrid pickup truck. See if you can guess which character from the new Batman film Stephen has chosen to portray (hint: It's not Morgan Freeman’s).
